At 19 days old, the baby shows slightly heavy respiratory sounds, good feeding, no vomiting, and is in good spirits. The respiratory sounds are more pronounced during deep sleep, with normal breathing. There is a slight tracheal traction. Can medication help? Neonatal pneumonia often manifests with minimal coughing, but during examination, the sound of phlegm in the trachea can be heard. Parents should not be careless as there is a large amount of bacteria breeding in the phlegm, and if not expelled in time, it can lead to pneumonia. Guidance: It is recommended to use a expectorant on the basis of anti-infection treatment to promote phlegm expectoration and recovery. I wish your baby a speedy recovery.
